How to use a domain I own to self-host services? (lemmy.world)

I'm not really sure how to ask this because my knowledge is pretty limited. Any basic answers or links will be much appreciated.

I have a number of self hosted services on my home PC. I'd like to be able to access them safely over the public Internet. There are a couple of reasons for this. There is an online calendar scheduling service I would like to have access to my caldav/carddav setup. I'd also like to set up Nextcloud, which seems more or less require https. I am using http connections secured through Tailscale at the moment.

I own a domain through an old Squarespace account that I would like to use. I currently have zero knowledge or understanding of how to route my self hosted services through the domain that I own, or even if that's the correct way to set it up. Is there a guide that explains step by step for beginners how to access my home setup through the domain that I own? Should I move the domain from Squarespace to another provider that is better equipped for this type of setup?

Is this a bad idea for someone without much experience in networking in general?

Exposing services over the public internet is not without risks, you might consider getting more knowledge before doing it

Every service you expose should require authentication and may need to handle bots

To gain knowledge about reverse proxies and dns without much risk exposure, you could start by setting up your custom domain name on your private tailscale network, here is an example of how you could do it

Now if you really want to expose services on the internet because you have devices that you don't want to connect to your tailscale network, you could use tailscale funnel, but only with your ts.net custom subdomain that they provide you, not with your own domain

There is an open issue to support custom domains https://github.com/tailscale/tailscale/issues/11563

I'm waiting for this to get resolved, in the meantime I have a vps with a reverse proxy connected to a tailscale container, that serves my services from my home network, so that I dont need a static IP or open a port in my home router
